My invention relates to windows, and has among its objects andadvantages the provision of an improved sash.

An object of my invention is to provide a sash in which three rails arepivotally connected and a fourth rail detachably connected with tworails to permit removal of said one rail and adjustment of the otherrails about their pivotal axes for opening the sash to facilitateinstallation and replacement of the glass pane.

Another object is to provide a demountable sash embodying two glasspanes arranged in spaced relation to provide an air space in the sash.

Another' object is to provide a sash which may be constructed ofmetallic rails together with means for cushioning the glass and toprovide an eifective seal between the glass and the metallic parts.

Another object is to provide a metallic sash construction embodyingnovel means for effecting a weather sealbetween the meeting rails of theupper and lower sashes.

In the embodiment selected to illustrate my invention, the sash I0comprises a lower sash rail I2, side rails I4 and the upper cross railI6. Side rails I4 are identical in construction and operation so thatthe description of one will apply to both. The rail I6 is detachablyconnected with the side rails I4, while the latter are pivotallyconnected at I8 with the rail I2 to permit the side rails to be pivotedoutwardly and downwardly for releasing the glass 2li or in oppositedirections for installation of the glass.

Figures 2 to 6 illustrate the corner construction of the top rail I6 andone of the side rails I4. Top rail I6 is illustrated in connection withthe lower sash of a two-sash window. Specifically, the rail I6 comprisesmetallic side walls 22 and 24 interconnected through the medium of abottom Wall 26 illustrated in Figures 3, 6 and 12. Bottom Wall 2E isdepressed to provide two spaced channels 28 for the reception of theupper margins of glass panes 2li. Cushioning means in the nature ofrubber-like material 32 is interposed between each pane and the walls ofits respective channel 28.

Wall 22 includes a right-angular ilange 34 arranged partly inoverlapping relation with a similar flange 36 on the wall 24, but inspaced relation therewith, see Figure l2. Between the flanges 34 and 36I mount a iiange 38 having a hook 40 inside which the flange 34 ispositioned. Flange 34 is provided with an inverted U-shaped rib 42terminating in a flange 44 extending across the flange 38 and providedwith a hook 46 along its outer margin. A bowed spring 48 is connectedwith a loop 5D depending from the hook 40 and engaging the wall 24 forurging the hook 46 in the direction of the arrow 52. The lower rail 54of the upper sash 56 is provided with a hook 53 reversed with respect tothe hook 4G and arranged to lie inside the latter for eecting aweather-tight seal between the upper sash 56 and the lower sash I0.Spring 43 urges the hook 46 into pressure relation with the hook 5t. Rib42 constitutes a grip through the medium of which the hook 46 may beadvanced against the tension of the spring 48 sufficiently far to bringthe hook in the clear of the hook 58 to permit raising of the lower sashor lowering of the upper sash.

It will thus be seen that the upper sash rail |6 is. hollow and cigenerally rectangular coniiguration in cross section. Inside one end ofthe rail |E I press a connecting member 60. Figure 6 illustrates themember 60 as including side walls 62 and 04 arranged to be pressed intofrictional relation with the walls 22 and 24, respectively. Member 60 isformed of sheet metal of materially heavier gauge than the sheet metalmaking up the rail l0. The originally flat metallic strip comprising themember 60 is bent to provide inner side walls 66 interconnected by abight 00 notched inwardly of one end at T0. The member is also fashionedto provide rectangularly shaped loops '12. The upper ends of the innerwalls 06 and the loops l2 terminate in a common plane slightly below theupper edges of the side walls 62 and 64.

Member 60 is pressed into the rail I0 to a point where the ends 14 ofthe walls 22 and 24 terminate flush with the bights 'I6 interconnectingthe side walls with the inner walls 70. Atr this time the ends of thechannels 20 abut the bight 08. Walls 16 and 'I0 of the loops l2 arerecessed at 80 for accommodating the channels 28. After the member hasbeen pushed home, the bights 82 of the channels 28 are struck partlyinto the loops T2, as at 8B in Figure 3, for xedly connecting the member60 with the rail. Figure 6 illustrates the Wall 2B as terminating shortof the ends 'M with the walls 22 and 2li flanged at 30 to extendunderneath the lower edges of the side walls 62 and 64 of the member 60.

In Figure 5, I illustrate the upper end of one of the sash rails |11,which rail comprises sheet metal fashioned to provide side walls 08 andan interconnecting wall 90 bent to provide troughs '92 corresponding tothe troughs 28 for the reception of the vertical margin of the glassassociated with that side of the sash. The outer wall of the rail I4comprises two anges S4 terminating in spaced right-angular anges 9%.Flanges 96 may ride between parting strips associated with the windowframe (not shown).

Within the upper end of the rail iii I position a connecting member 98which is fashioned of sheet metal considerably heavier gauge than thesheet metal from which the rail I4 is formed. Member 08 includes sidewalls |00 which terminate in loops |02 terminating in an invertedU-shaped element |04 fitting snugly between the inner side walls 06 ofthe member 60. The end |00 of the U-shaped element |04 lies against theinner face of the bight 68, while the end |08 terminates flush with thebights 76. The upper end of the rail I4 terminates substantially flushwith the faces ||0 of the member 08.

Faces H0 are cut away at ||2, while the walls H4 of the loops |02 arecut away at HB, see Figure 14. When the member 98 is shoved home insidethe rail I0, the channels 92 will be pressed between the walls |00 andthe inner side walls ||0 of the loops |02. With the member 98 properlyassembled with the rail I4, the bights are Struck partly into the loops|02, as at |22 in Figure 3. Thus the member 98 will be effectivelyconnected With the rail I4. Inner walls 66 of the member 60 are recessedat |24 to receive the end extensions of a pin |26 passing through theWalls |06 and |08 of the U-shaped element |04. With the members 60 andS3 assembled, a key shank |204 is pressed between the side walls |05 and|08 with itshooked end |30 slipped through the slot 'l0 and hooked overthe bight E3, as in Figure 3. Shank |23 includes a lug |32 arranged tobe positioned inside the opening |34 in the bight of the Ueshapedelement |54.

Shank |28 includes a right-angular extension |30 having an opening |38for the reception of the usual weight cord |40. Thus the Weight cordpull effective on the key shank |28 will electively support it in theposition of Figure 3, at which time the member 60 is restrained fromseparation from the member 9B. Lug |32 restrains the key shank |23 fromrelative longitudinal movement with respect to the walls si and |08. Pin|20 restrains the member B0 .from relative longitudinal movement withrespect to the member 98. Thus the two members effectively connectedinto a unitary structure, but may easily be disconnected by merelyremoving the key shank |23.

Referring to Figures 7 to 1l inclusive, the lower end of the sash railIll is of the same construction as the upper end illustrated in Figure5. Within the lower end of the rail lli I position a connecting member|22 comprising sheet metal bent to provide a U-shaped element |22connected with side walls |26 through the medium of right-angular runs|43. Side walls H56 are bent to provide loops |"0, The walls |52 and |54of the loops are cut away at |56 to accommodate the channels 92 whichare pressed between the side walls |46 and the inner walls |58. Figure 8illustrates the bights |50 of the channels 02 as being struck inwardlyo'i' the loops 50, as at |62 to effectively connect the member M2 withthe rail I4. The U-shaped element lll of the member |52 is arranged tobe irictionally positioned between the inner walls |2 of the member |64connected with the lower sash rail I2. Inner walls |62 are connectedwith outer walls |66 through the medium of bights ltl. The walls |06have their upper edges terminating Hush with the walls |62 which arelocated below the edges Il!! of the side walls |06. The side walls ofthe member |62 terminate in loops |12, and the walls |72 and |16 of theloops are cut away at |16 to accommodate the channels |78 of the rail|2.

Figure 7 illustrates the member Iiipressed into the rail l2 to theposition where its end |26 terminates substantially ilush with the bight|80 interconnecting the inner walls |02. The bights |82 of the channelsH3 are partly struck into the loops |10, as at |04 in Figure 8. Thus themember |04 is xedly related to the rail i2. Figure 10 illustrates theouterface of the rail l2 at |86, which outer face terminates in adepending U-shaped` element |88 arranged to have overlapping relationwith the vertical ledge E92 of the window sill |92 for sealing purposes.The inner wall |92 is fashioned to provide aninwardly extending iiangeIBt'S which facilitates manual manipulation of the sash.

U-shaped element |02 is positioned between the inner walls |62, at whichtime the edges |00 of the element Ifl bear against the bight |30. Thewalls of the U-shaped element |136 are provided with aligned openings290.. for loosely receiving a pin 202 extending through openings 2&4 inthev side walls |06 and riveted, as at 200 in Figure 7. Bight |30 isprovided with an opening 200 for the reception of the reduced end 2|0 ofa key-bar 2|2whlch is pressedbetween the. pin 202 and the bight 2| 4 ofthe U-shaped element |44. The bar 2I2 ts snugly between the walls of theU-shaped element |44 and includes an under-cut 2|2 for the reception ofthe bight 2I4. With the key bar 2|2 in position, the bar I4 is latchedagainst pivotal movement with respect to the bar I2. However, removal ofthe key bar 2|2 will permit the rail I4 to be pivoted about the pin 202as an axis. In Figures 8 and 9, I have illustrated the U-shaped element|44 as being curved at 2|6, which curvature is concentrically related tothe axis of the pin 202. Figure 8 illustrates the edges |98 as lyingsnugly against the bight IBI). Thus the parts |42 and |64 will bepositively latched against relative pivotal movement.

Channels |18 function in the same manner as the channels 28 of Figurel2. Key bar 2I2 is illustrated as being provided with an opening2|8which may be utilized for connection with a sash cord for an upper sash(not shown). In Figure l1, I illustrate a corner piece 220 forconnection with the lower corners of the sash. Corner piece 22thincludes a wall 222 terminating in a U-shaped flange 224 of the sameconfiguration as the flange |23 and arranged to be brought intoend-toend abutting relation therewith when the corner piece is attachedto the sash. The side wall 222 and the side wall 226 each includes aninset wall 223 which is arranged to ride on the upper edges of the walls|62 and |66.

Figure 8 illustrates the corner piece 220 in position, at which time theloops 236 lie between the upper edges of the narrow runs of the walls|62 .and |66 and the right-angular runs |48 of the member |42. TheU-shaped element 232 of the corner `piece 22B is aligned with theflanges 96 on the rail I4. The wall 234 of the connecting member 22|) isslotted at 236 so as to provide accommodation for the corner 238 of theU-shaped element I44.as it is pivoted about the pin 202 as an axis.

Between the twoglass panes 2IJ I position cross rails 24D for ornamentalpurposes. The lower ends of the two vertical rails abut the wall 242 ofthe rail I2, the upper ends of the cross rails abut wall 26 of the uppersash rail I6, while the enids of the horizontal cross rails abut thewalls 90 of the sash rails I4.

It will thus be seen that I have provided a window sash embodying twoglass panes so arranged as to provide an effective air spacetherebetween. The outer margins of the glass panes are effectivelysealed with respect to their associated sash rails. The glass panes haveweather sealing relation with the sash rails, and the glass panes andthe sash rails are effectively connected without the aid of glazierspoints, putty and the like. The panes are quickly installed by merelyfirst positioning the panes in proper connected relation with the lowersash rail I2 and pivoting the i sash rails I4 into position. The uppersash rail IE is then placed in position and keyed. The sash is thenready for use.

Without further elaboration, the foregoing will so fully illustrate myinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.
